Your testicles produce sperm that mix with seminal fluids while moving through the tubes called the vasa differentia. These seminal fluids thatare part of semen keep sperm alive and active. Vasectomy is a procedure used to block each vas deferens by cutting, clamping or sealing it in some way. This will keep sperm out of the seminal fluid and even if you ejaculate after vasectomy, your semen won't contain sperm, so avoid pregnancy after vasectomy. However, many people ask if there is a chance of making someone pregnant after vasectomy. Keep reading to find out more about the topic.

Pregnancy After Vasectomy: Is It Possible?

It is possible but only happens with the ratio of 1 in 1000 cases during the first year of vasectomy. Many studies have confirmed that there is less than 1% chance of becoming pregnant after vasectomy. The best thing to ensure you don't have to deal with pregnancy after vasectomy is to have a semen analysis done – it's called a semen specimen after vasectomy (SSAV) precisely. This analysis will confirm if you're good to leave alternative methods of contraception.

So, there is a possibility of becoming pregnant after a vasectomy, even though it's very low. Still, it is a good idea to not overlook any pregnancy symptoms your partner may be experiencing.

Pregnancy After Vasectomy: How Does It Happen?

You already know that it's very rare to experience pregnancy after vasectomy, but it's possible. It usually happens in one of the follow three primary ways.

1.  Having Sex with Your Partner Before Confirming Your Sperm Count Is Zero

What it means is that you may have live sperm present in your semen even after several months of a vasectomy. You may end up making your partner pregnant if you have unprotected sex during this time. Most doctors believe that a man is usually sterile after a couple of months of a vasectomy or 20-25 ejaculations. These are only guidelines, so it is better to have one semen analysis performed after the procedure to ensure it is safe to have sex with your partner without worrying about pregnancy.

2.  Natural Reversal

Also called a recanalization, it refers to a condition when your sperm manages to come out of your vas deferens due to microscopic channels, which may have formed in your scar tissue. A post-vasectomy semen analysis will confirm if you have any of these micro channels developed after the procedure. Late recanalization isn't that common and may happen in 1 out of 4000 vasectomies.

3.  Surgical Error

It is quite uncommon, but a vasectomy can fail due to a surgical error. This will again lead to pregnancy after vasectomy. Make sure to consult a skilled doctor before undergoing the surgery. A GP can help you with vasectomy, but you will be better off asking an urologist take care of everything to reduce the risk of surgical errors.
